I just configured a Virtual Box following the docs. I am getting

ltdb: tdb(/var/lib/samba/group_mapping.ldb): tdb_mmap failed for size 77824 (Cannot allocate memory)

when trying to connect to FTP. I think the same configuration worked before. What's wrong with this? I tried removing samba but still have the same problem

Your virtual machine is out of memory. Try to give it some more.
